Worried Jay Z beefs up security for Beyoncé and baby Blue

As one of the most in-demand stars on the planet it's not a surprise that Beyoncé Knowles has been the victim of over-excited fans more than once. Nonetheless, this has got hubby Jay Z a little worried, so he's decided to take some rather drastic measures to protect his girls.

Jay Z is so worried for his family's safety that he's doubled their security.

The rapper has hired five ex-Mossad agents - the former Israeli secret service squad - at a cost of £2million for his wife Beyoncé and daughter Blue Ivy.

A source told Now magazine: "Jay's worried about the possibility of kidnap so he's taking no chances."

The extreme measures come after Bey was pulled off stage by an over-excited fan in Brazil.

The 32-year-old singer was performing in Rio, on a platform surrounded by her crowd.

As she moved closer to her fans, one aggressively tried to grab her and pull her into the audience as she attempted to fight him off.
